In an acute seizure emergency, which set lists the first-line benzodiazepine dosing and routes?

• A. Lorazepam 0.1 mg/kg IV (max 4 mg); Diazepam 0.15–0.2 mg/kg IV (max 10 mg) or rectal; Midazolam 0.2 mg/kg IM/IN.
• B. Phenytoin 20 mg/kg IV; Valproate 40 mg/kg IV; Levetiracetam 60 mg/kg IV.
• C. Lorazepam 2 mg IV; Diazepam 40 mg IV; Midazolam 10 mg IM.
• D. Diazepam 0.5 mg/kg PO; Lorazepam 0.5 mg/kg IM; Midazolam 0.5 mg/kg IV.

Answer: (D)

In acute seizure emergencies, giving a benzodiazepine quickly is the最 effective way to stop the seizure, because these drugs rapidly enhance GABAergic inhibition in the brain and curb excessive electrical activity. Dosing should be weight-based so the dose is appropriate for the patient’s size and still safe. Using multiple routes ensures you can deliver that medication promptly no matter the setting or how quickly IV access can be obtained.

This option shows a flexible, weight-based approach across three routes to maximize speed and accessibility: diazepam by mouth provides an option when the patient or caregiver can take medication orally; lorazepam by intramuscular injection offers a rapid, reliable route when IV access is not yet available; and midazolam by the intravenous route delivers the fastest onset when an IV line is already in place. Together, these routes cover common real-world scenarios and emphasize getting benzodiazepine therapy into the system as rapidly as possible.

The other choices either involve anticonvulsants not used as first-line rescue therapy in this setting or present dosing and routes that aren’t aligned with the goal of rapid, weight-based benzodiazepine administration for seizure cessation.
